Memory Flashcards
What are the 3 types of LTM
-Episodic
-Semantic
-Procedural
Types of LTM
Describe episodic memory
- Episodic memory is the memory of event or personal experiences you’ve had such as your first day of school
Types of LTM
Describe Semantic memory
- Semantic memory is our memory of facts and meaning in the world for example what the word elephant means
Types of LTM
Describe Procedural memory
- Procedural memory is the memory of actions or skills; how we do things, examples are how to ride a bike or how to swim
2 strengths
2 Evaluation Points about the different types of memory
- Another strength of different types of long-term memories is that they are supported by case studies of amnesiacs. For example, Clive Wearing lost most of his episodic memory but not his procedural memory as he could still play the piano. This shows there are different kinds of LTM.
- A strength of the idea of different types of long-term memories is that brain scans show that different types of LTM relate to different brain locations. For example, episodic memory is found in the right prefrontal cortex whereas semantic memory is associated with the left prefrontal cortex. This supports the idea that that there are different types of LTM.

Study of Encoding
Aim of Baddeley’s study
His aim was to see how info was encoded into the STM and LTM
Study of Encoding
Method of Baddeley’s study
- Group A —> similar sounding words,
- Group B —> dissimilar sounding words
- Group C —> words with similar meanings,
- Group D —> words with dissimilar meanings
- Groups A and B were asked to recall their words immediately (testing STM) whilst Groups C and D were asked to recall their words after 20 minutes (testing LTM)
Study of Encoding
Results of Baddeley’s study
- When the participants had to recall immediately (STM recall) they tended to do worse with the acoustically similar words
- When the participants recalled after 20 minutes (LTM recall), they tended to perform worse with semantically similar words
Study of Encoding
Conclusions of Baddeley’s study
This suggests that information in the STM is encoded acoustically and the information in the LTM is encoded sematically

2 weaknesses
- We cannot say for sure that other people would have acted in the same way during this study. Baddeley used students and therefore we cannot generalise the findings to the rest of the population – especially people who aren’t students. this is a disadvantage because we are not able to apply the findings to real life.
- Another weakness is the experiment took place in a lab setting; unnatural for participants. Being in a different environment might have made them feel nervous or under pressure; could have lead to inaccurate results. We can say this study lacks ecological validity and it is therefore a disadvantage as the results might be inaccurate.

What are the 3 types of encoding; explain them
-Visual (encoded based on how it looks)
-Acoustic (encoded based on how it sounds)
-Semantic (encoded based on its meaning)
What is encoding
Encoding means information that is input in the brain must be changed into a form where the brain can hold it
What is storage
Storage is where the brain holds the information that was encoded
What is retrieval
Retrieval is when the brain finds the piece of information and brings it back from the brain so that it can be used
What are the different ways of retrieval
- Cued Recall (info is recalled when given a cue; given a hint)
- Recognition (for example, you are given multiple choice questions, you decide the right answer out of those few answers)
- Free Recall (you recall information without any cues)
What are the 3 main components of the Multistore Model of Memory
- The sensory store
- The STM store
- The LTM store
AO1 of the Multistore Model of Memory
- Information flows through the sensory, short term memory and long term memory stores
- Information is transferred from the sensory store to the STM store if we pay attention to it
- Information is transferred from the STM store to the LTM store if it’s rehearsed
- In the sensory store, capacity is very high and duration is less than half a second unless paid attention to
- In the short term store, info is coded acoustically, capacity is about 7 items and has a duration of less than 30 seconds unless rehearsed
- In the long term store, info is coded semantically, capacity is unlimited and duration is up to a lifetime
2 weaknesses
AO3 of the Multistore Model of Memory
- The multi-store model of memory does not explain how you can remember some information even though you have not rehearsed it and also struggles to explain why we can forget information that we have practised and rehearsed.
- The multi-store model has been criticised for being oversimplified. For example, it states we have one single long-term memory store. However, other research evidence has shown that there are several
types of long-term memory; procedural, episodic and semantic.
don’t explain how u can remember info, critised; several types of LTM
What was the aim of Murdocks Serial Position Curve Study
Murdock wanted to see whether the position of a word in a list affected people’s ability to recall it
